This was a long drawn out process - over a month without getting to the in person interview. First they ask you about biographical information especially relating to the country. Then there is a hour writing test about technology, why you would make a good fit, and what is annoying about applying to jobs. After passing this there is a friendly chat with a kind recruiter with, as stated, math questions and facts about the company. Don't let them get your hopes up. After all this there is a 45 minute Skype call, which was completely different from the "we're a nice company that only wants talented nice people" attitude. The interviewer seemed uninterested, bored, and went through the motions without responding to any of the answers or try and make an effort to explain the role. People from other office rooms kept popping in to laugh with the interviewer about outside work. Overall, this was disappointing as they didn't bother to make a connection...leaving me inflated and unsure about wanting to work there in the first place.

As mentioned by previous answers, the process is writing exercise, phone screen with recruiter, skype interview with manager and on-site interview. All the people I met are friendly and polite. The whole process took 2 weeks. They moved very fast with me maybe because I'm a local candidate. If you have plan to apply this position, be prepared to face-to-face math question and estimation question. There are a lot of them. And of cause, research indeed product before any interview, try different feature and think about every thing they have on the indeed website. This is important to show that you are prepared to the company and this position.
